I've been meaning to get this written up and posted, but have just been busy. I hope what I've put together is detailed enough. People can send me details or add info, and I'll update the file.

Awesome write up!!!!!!!!!!!!!:thumbup:

Where can I get the PCB(printed circuit board)?

I thought this was for a SIM Access Profile Bluetooth conversion not the secondary air pump :$

The PCB and Project Box can be purchased from Radioshack, but I don't have part numbers for them. They carry a good selection in store, so as long as you get a PCB that is at least 2" by 3", and a box that can hold that, plus at least 1" tall, you shouldn't have a problem.

Thank you for this DIY!

This a great DIY.

I am deleting the SAP and the valve soon and I need you to direct me to a site that sells the Block Off plate for the valve. I saw a retailer that had it but lost the link.

Many thanks. This Forum is very good.

Drewfus2101 03-17-2011 08:54 AM

This is the only one that I found for the M54:
http://store.vacmotorsports.com/vac-...ate-p1744.aspx

But I'm too cheap, so I made one from some 1/8" steel I got at Lowes. It was a paint to cut with a hack-saw, but it was shaped the same.

However, I remember reading that BMW had an OEM part that fit. I did some research a while back, and wasn't able to find the part number. I just did some more digging, and they show the part on the diagram for my car, but don't give the number. But for the EURO model, the list the number. I put that in at ECS, and I got a hit.

Part #10 looks like the right one to me. I guess the EURO ones didn't come with the egr valve. ECS has the part for $7, which is much better than the other one, and better than making one too.

RBK333 03-17-2011 10:35 AM

Hey thanks for the link. I will explore getting that part.

Is it true that pre-03 cars won't get a SES light?

drumbum624 05-25-2011 02:22 PM

If i were to use that part to block off where the EGR connects to the block, how should I go about closing that other little vaccum line that connects to it, golf tee? Also if I deleted my SAP without the sim, would my car still run the same and I got an SES or will it effect engine performance in any way?

The car will show a CE/SES light if you remove the SAP without using a simulator.

Performance will not be affected by removing the SAP, which pumps air into the exhaust for about a minute on cold days. Otherwise the valve is closed and the SAP is not operating.

The low flow code (due to SAP removal) will not affect the car, but you will not know if you have a legitimate new code without constantly reading if new codes have been registered since the SES light would be already on.

drumbum624 06-02-2011 03:24 PM

Thanks, thats no problem cause I already have a light for my post cat 02 sensors. I don't mind checking occasionally for new codes.

But about that other vaccum line...shut it off with a golf tee?

Has anyone confirmed whether or not this will work with the MS45.1?

fadeaway 05-10-2012 12:53 PM

I'm hoping someone could give me a bit of insight into the 04+ models.

There appears to be two different types of SAP systems for our cars. I just took a look at mine and I have the newer version with an air filter. Part number 3 is a mass air flow sensor. I don't even see a connector for control signals on either SAP. Is it hiding somewhere?

The plug is not really visible from the top. It is on the bottom of the unit. Easy enough to get to though.

fadeaway 05-20-2012 09:51 PM

Hrm. I wonder whether or not the mass air flow sensor requires extra circuitry. I haven't been able to find another thread with this new system. I'll have to start tinkering on my own.

Thanks, but what circuit board do we use, can you take pics of your circuit board finished?

SUHLeen 05-21-2012 08:16 AM

I'm getting a CEL from the sap and I have headers with no cats, but I have an 01. I do not need the SAP since I have headers, but I do not want a CEL as all my other CEL's are off except two that I think are from bad pre o2 sensors.
